▎ 摘　　要

The efficient utilization of the abundant and economical solar energy has received tremendous attention due to increased environmental and energy concerns. In this report, a plasmonic Ag-AgBr photocatalyst functionalized with graphene oxide-Pd was successfully fabricated and used as an efficient visible-light-responsive photocatalyst for the Suzuki coupling reaction. The integration of plasmonic Ag-AgBr with Pd nanoparticles supported on graphene oxide enabled efficient visible light harvesting for the catalytic reaction on the heterojunction structure. A possible catalytic mechanism for the highly efficient photocatalyst is proposed. This work provides a convenient means for the design of efficient catalysts that are composed of a photocatalyst and a catalytically active transition metal for various organic transformations driven by visible light.
